Fortnite Season 5 is officially underway, and there's plenty of new content for players to sink their teeth into. We've already extensively covered the changes and additions, but we also wanted to collect all the new tips and tricks you'll have at your disposal.

First and foremost, you'll want to know about the changes made to shotguns--especially considering how significant they've been to player strategy in the battle royale. Shotguns will now indicate how many pellets actually hit, with visible markers appearing within the reticle. You won't be able to cycle between two shotguns like you could before though, as there is now a short period of time after firing a shotgun where another shotgun can't be fired. Measure your shots carefully, or just find another way to kill someone.
